Rif : Ouazzane, Ouargha subwaterched of Sebou v., Fifi rills spr., 15.04.2005 , 1300 m , 1 male , 1 female , 11L (ERR). Distribution ( Fig. 8 ). A West Mediterranean species occurring in France ( Le Doaré & Vinçon 2006 ), Spain and extending in the Moroccan mountain ranges through the Rif and up to the northern edge of the Middle Atlas (Tierno de Figueroa et al . 2003, Errochdi et al . 2014 and Vinçon et al . 2014). Ecology. Larvae are cold stenothermic and crenophilic, occurring only in high altitude brooks and springs ( 1200–1800 m ) ( Aubert 1961 , Errochdi & El Alami 2008 , Errochdi et al. 2014) ( Figs. 13 –15). In Spain it is more eurytopic ( 15–1800 m ) ( Sánchez-Ortega et al. 2003 , Tierno de Figueroa et al. 2003) and in septentrional localities of France , it only occurs in the foothills, and associated with calcareous substratum (Reding and G. Vinçon, personal observations). The immature larvae appear to be detritivorous and gradually change to become more herbivorous ( Azzouz & Sánchez-Ortega 2000 ). The adults emerge in spring (III–VI).
